Hi all. I've noticed that BooBoo gets these coughing spells. I described it to the vet and he says it sounds like fur balls. He does use his litter box so I don't think there is an obstruction or anything like that, but I'm not convinced this is the problem. I'll get some of that fur ball stuff in a tube for him today, but could this be something else? I have no idea if this was a problem before we got them because the previous owners will not offer up any more information on him to me. I do know that the previous owners smoked in their home and that certainly could not have been good for him. Is this a typical problem for a Felv cat ? If so, should I be getting him back to the vet for some kind of medication?
